Par38 bulbs.... How much area per bulb?

Jeff000 · 07/24/2012, 07:30 PM

I've decided on using Par38 bulbs, the rapid led ones.
How large an area do they cover for growing? Like a 10x10 for growing hard corals and then softies around the edge of the lighting focal point.

Anyone with experience.

I have one rapid led par38 bulb over my 10g and if I wasn't in the process of upgrading I would add a second one. I only have zoas and lps.

Oh wow, that's significantly less then I was expecting, maybe I will just do DIY then.
